Sometimes we deliberate - for example when we plan a long trip or - if we are not math wizards - when we solve long division problems. However, if we deliberated every time we acted we would never get through the day. Most of the time, we act for reasons without deliberation. I am not just talking about cases of simple, habitual action, like brushing your teeth, but also about more sophisticated action.

I am not committed in any way to the traditional concept of character - the concept of "character trait" as involving predictable behavior. I am committed to a view in the neighborhood - the view that the moral worth of one's actions depends on the quality of will expressed in them.

Other things being equal, ill will is worse than moral indifference (as in causing suffering for money vs causing suffering to cause suffering), though things are rarely equal.

Moral virtues and intellectual virtues are very different from each other, and moral virtue has to do with motivation, not cognition. Moral virtue requires a human level of intelligence, but it doesn't require that one be an intelligent human.

I don't think we are all irrational every time we fail to see through an argument in a book, but suppose it's true about you. You are still more rational than you think you are. You are irrational in a minor way - believing a misguided theory of the nature of rationality - but rational in a major way - you respond well to probabilistic evidence as you go through the day.

"Externality" is a different phenomenon from akrasia and doesn't always come with it. The set of desires and actions from which one feels alienated isn't always the same as the set of desires and actions of which one disapproves. It has been pointed out that you can disapprove of something inside yourself but still experience it as yours ("damn it, here I go again!"). In addition, you can approve of something inside yourself but feel like it's not yours ("when the emergency sirens went off, it was as if someone calmer and more reasonable took over and knew just what to do").

If I make a stupid decision but don't execute it because I'm, say, lazy, then I'm lucky, not rational. However, at other times a person acts for good reasons just as she does what she thinks she shouldn't do, not knowing that they are good reasons. Just like sometimes we are a lot less rational than we think we are, it is also true that sometimes we are a lot more rational than we think we are.
